Fibroblast growth factor receptor 4
Hydroxyaryl protein kinase
Protein tyrosine kinase
Tyrosine kinase related to fibroblast growth factor receptor
FunctionReceptor for acidic fibroblast growth factor. Does not bind to basic fibroblast growth factor. Binds FGF19.
Tissue specificityExpressed in gastrointestinal epithelial cells, pancreas, and gastric and pancreatic cancer cell lines.
Sequence similaritiesBelongs to the protein kinase superfamily. Tyr protein kinase family. Fibroblast growth factor receptor subfamily. Contains 3 Ig-like C2-type (immunoglobulin-like) domains. Contains 1 protein kinase domain.
Post-translational modificationsGlycosylated. Phosphorylated on tyrosine residue (By similarity). Phosphorylation requires the presence of a functional (phosphorylated) FGFR1 and not necessarily by means of FGFR heterodimerization.
Cellular localizationMembrane. Isoform 2 may be secreted.
